CLP triggers segmentation fault when compressing tarred openstack log

[haiqi96]

Bug

When compressing the openstack.tar.gz logs (https://zenodo.org/records/7094972), CLP fails a with segmentation fault. Note that CLP can compress uncompressed openstack logs without any issue.

I tried to create a tar.gz from the plain log that CLP can compress, and the new tar.gz still triggers the segmentation fault.

Verified that commit 4f9ed0a doesn't have this issue.

CLP version

5d6ff54

Environment

Ubuntu22.04

Reproduction steps

clp c output openstack-24hr.tar.gz
